This lighting is effective for viewing on both sides of traffic within a radius of 5 meters.

  • This solution was created exclusively for long-range illumination of the space in front of the user, regardless of whether he is standing or moving, and regardless of whether it happens during the day or at night. That is, this solution is used to obtain visual information about the situation in front of the user in conditions of insufficient or limited visibility.

  • flashlights with a wide angle of illumination, soft side illumination and a smooth transition to it from the central beam allow you to get much more natural lighting at short distances. They are good, for example, for tourism, because they make it easier to navigate in space and relieve additional strain on the eyes.

  • the user sees the light surrounding him not from the luminous flux, but from the external environment.

  • the spatial density of the light flux is determined by a narrow solid angle, so the user does not see the initial part of the glow, but clearly sees objects illuminated by a narrow beam at a distance of several meters. And for work, it is necessary to illuminate the initial section of light radiation and, at the same time, in a diffuse form (like the glow of a table lamp in a wide-angle solid angle.), And not in a beam concentrated in brightness.

  • the theoretical premises are based on the principle of the glow of a classic table lamp.
  • a table lamp should give an even and soft glow. Glare and flicker, which adversely affect vision, should be excluded. At first, the eyes quickly get tired of this, and over time, visual acuity decreases markedly.
  • the ceiling In desktop appliances with a standard cartridge, the ceiling must have a depth in which the light bulb will be completely hidden. If the bulb is at least half out of the ceiling, its glow will blind the eyes, which will negatively affect vision.
  • the lamp should be moderately bright - the luminous flux should not exceed 400,700 lm (lumens). There is a division into cold, neutral (daytime) and warm white. Maximally contributes to the increase of working capacity and concentration of attention, while not letting the eyes get tired, day or warm white shade, corresponding to 3600 ; 3800 K. This value can be considered optimal for table lighting.
  • LED lamps are the best option as a table lamp. They almost always have compact dimensions with quite sufficient brightness of the glow. They are reliable and safe, as they do not heat up to high temperatures, and even if one of the LEDs burns out, the rest continue to give light. The LEDs light up immediately, do not blink or flicker, give an even, calm light. When choosing a panel version of LED lamps, it is recommended that there be at least 12 of them, which will contribute to a more uniform luminous flux. According to the present utility model, a design of a lighting device worn on the user's head is proposed, which allows simulating lighting by analogy with the lighting of a classic table lamp.
  • the head-worn lighting device comprises means for attaching an LED light source placed on the user's head.
  • This fastening means is a headband 1, worn on the head perpendicular to the direct view of the user with the location of the temples 2 (arcs) of the headband in the area of the user's ears. That is, the headband (both narrow and wide) is put on from above with a downward movement and is located on the head behind the frontal part of the head, but up to the back of the head.
  • This headband follows the shape of traditionally used headbands to hold the hair on the head so that the hair does not interfere with work. It can be made of polymeric material, metal, wood. The essence of its design lies in the fact that with its arcuately curved shape, the end parts, which are the arms 2, are elastically deformable, due to which the rim is held on the head.
  • the rim can be made with a comb, which makes it possible to prevent the rim from moving on the head when the latter is tilted.
  • the use of the rim as a means of fastening the LED light source allows you to transfer the position of the light source to the head area behind the forehead. This arrangement imitates the effect of a cap (plafond in a classic table lamp), due to the fact that the zone of light emission and the area of the light flux of maximum brightness are removed from the user's field of vision.
  • LEDs 3, recommended not less than 12 pcs. quantity are located on the board, which is placed in a separate flattened (flat) case 4, the thickness of which is determined by the dimensions of the LEDs, the thickness of the case walls and the thickness of the diffuser through which the light radiation passes.
  • Essential for this part of the device is not the size of the case and not the number of LEDs, but the weight of the case with the board and LEDs, since it is the weight that determines the positional stability of the lighting device on the user's head (which is held due to the elastic forces of pressing the temples to the temples). in the user's ear area). Therefore, the body is made of a thin-walled polymer, and the diffuser can be made of polycarbonate.
  • the diffuser is used to evenly distribute the flow of light. This is affected by the relief, texture, shape of the diffuser. Due to multiple re-reflections from microparticles located in the thickness of the material, the bright light from the LEDs is redistributed almost throughout the entire volume of the diffuser and creates a soft stream that is comfortable for human vision.
  • FIG. 1 shows an example of the considered head-mounted lighting device, in which the housing with LEDs is rectangular in plan on the diffuser side.
  • the attachment of the body to the rim is made on a small section of the rim between the temples.
  • FIG. 2 shows an example of execution in which the body is made arc-shaped and attached to the rim in the area between the elastic arms, while expanding the surface of the LEDs.
  • Fig. 3 shows an example in which two bodies are fixed on the rim, spaced relative to each other (like "lugs"). These two cases can be separate independent or interconnected by a common jumper, forming, in fact, one case of the original in form.
  • the shape of the housing in plan view from the diffuser side is not significant, since it does not affect the achievement of the technical result.
  • the LED light source is located on the board enclosed in the case, and is a set of LEDs 3, facing the optical elements through the diffuser of the case in the direction of the direct view of the user.
